The app looks very promising I just discovered it, but It's very slow when you click to analyze a component, taking minutes to finish
0.2.2 didn't detect the web components I was trying to understand. It also overrode the `throttle` method from my application, causing all kinds of strange issues.
This extension is amazing!!!
Really helpful.
This extension is so helpful. It helps track and dive into each webcomponent. It's like having the knobs of Storybook on a live website.
